Stainless steel barbed rope service life is, of course, the longer the better. But do you know how to extend the service life of stainless steel barbed rope?
- The composition of hot dip galvanizing layer is composed of hot dip galvanizing layer, which is composed of iron zinc alloy between iron matrix and surface pure zinc layer. The shape of the workpiece is formed by the iron zinc alloy layer in hot dip, so that the iron and pure zinc layer touch outstanding. When the iron workpiece is immersed in a molten zinc solution, the initial zinc and iron (body) are formed at the interface. This is a crystal made up of zinc atoms in the solid metal iron. When two metal atoms are fused together, the gravitational force between the atoms is very small.

The different spacing of the thorn rope is mainly in order to save costs to consider, because if they are too close, then obviously a little waste of resources, but the installation is too sparse will not work. Usually the bottom spacing is about 10cm, and the top is up to 20cm, this is because the higher the place is more difficult to climb over, usually more than one meter without the help of tools it is difficult for ordinary people to climb over, and the bottom because of the relatively tight can prevent personnel from drilling in the past.
- Under normal circumstances, the organic matter contained in galvanized wire can make electroplating speed significantly reduced. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath. Zinc is a silver-white metal, brittle at room temperature, soluble in both acid and base, known as amphoteric metal.

The reason why there are black spots in wire mesh welding is that the action of wire feeding should be timely filled in the melting time, and the development should be appropriate. There is no argon gas, long burning, large current, long distance, blunt tungsten needle and high molten pool temperature are the fundamental reasons for blackening. Continuous burning, is about active welding machine energy selection, machine welding will appear black spots.

① The diameter of galvanized iron wire for drawing shall not be less than 4mm, and the diameter of galvanized iron wire for binding shall not be less than 2.6mm.
- Galvanizing can be done by zincate galvanizing or chloride galvanizing. Appropriate additives should be used to obtain a coating that meets the requirements of this standard. Light treatment should be carried out after light plating. The parts that need to be dehydrogenated for passivation should be passivated after dehydrogenation. Before passivation, 1%H2SO4 or 1% hydrochloric acid should be applied for activation for 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
